GB/T 5686.1-2022 Ferromanganese,ferromanganese-sili4con,nitrogen-bearing ferromanganese and manganese metal—Determination of manganese content—Potentiometric method,titrimetric method after ammonium nitrate oxidation and titrimetric method after perchloric acid oxidation
Abstract
This document describes the methods of determining the manganese content in manganese-iron alloys, manganese-silicon alloys, manganese-iron nitrides, and metallic manganese using potentiometric titration, ammonium nitrate oxidation titration, and perchloric acid oxidation titration. This document is applicable to the determination of manganese content in manganese-iron alloys, manganese-silicon alloys, manganese-iron nitrides, and metallic manganese, with a measurement range (mass fraction): 50.00%~98.00%. Method I is not suitable for determining the manganese content in manganese-iron alloys, manganese-silicon alloys, manganese-iron nitrides, and metallic manganese with a chromium or vanadium content (mass fraction) greater than 0.4%.
